My inlaws have a toy pomeranian that always travels with them and was my wife's childhood pet. She absolutely adores her (she is very cute) and also wants the pom to come visit every time. Normally I wouldn't mind, we have two medium size dogs and they love friends. There are two problems though: 1. the pom is untrained and pees and defecates inside, its to the point where at their house they just leave a towel on the floor for it to pee on. 2. It is an alpha type, it constantly snips and tries to aggress on my dogs, potentially causing an issue. My pitmix is a baby and lets her do it, but my other dog is also alpha type and, when seeing the pom biting at my pit, immediately flared up into prey drive. I want my wife to see her old dog so I am willing to compromise and have her separate from ours, but only outside because if she's inside she will pee wherever and whenever. I have made this clear, but my wife and inlaws think I am overreacting and have willingly disrespected this boundary multiple times. I went out for a quick run and came back, my dogs outside and the pom running around the house. Entire family says oh its just for a second, but then I see the bottle of Resolve Dog Stain cleaner on the counter, meaning they are willingly breaking the boundary and are prepared to just ask for forgiveness. I have tried multiple times to talk to my wife and each time she will blatantly ignore me and walk away or mockingly "I cant hear you" and shut me out. I understand I am fighting a battle with her and a separate one with all of them, but I cant help feeling that IATA. I want my wife to see her family pet she adores, but its not enough for her just be outside with the dog it HAS to be inside too. So, AITA if, they disrespect my boundary again, completely shut it down and not allow the dog over anymore? Sorry i am losing my mind over here
